Fasolasuchus is an extinct genus of loricatan. Fossils have been found in the Los Colorados Formation of the Ischigualasto-Villa Unión Basin in northwestern Argentina that date back to the Norian stage of the Late Triassic, making it one of the last rauisuchians to have existed before the order became extinct at the end of the Triassic.[1][2]

Description

It is quite possibly the largest known member of Rauisuchia, with an estimated length of 8 m (26 ft)[3] to 10 m (33 ft),[4][5] even bigger than the prestosuchid Saurosuchus at 7 metres (23 ft) in length.

This would make Fasolasuchus the largest terrestrial predator to have ever existed save for large theropods.[citation needed] Like Saurosuchus, it had only a single row of caudal osteoderms, unusual among rauisuchians.[6] It also had a hyposphene-hypantrum articulation that gave the vertebral column extra rigidity. This feature is also seen in several other rauisuchians such as Postosuchus as well as saurischian dinosaurs.[7][8]
